Now, that I have explained three of the selection methods, let me off a couple of tips about selections. When you want to select more than one area of a picture with the Magic Wand Tool, you can do so by pressing the Shift Key when making multiple selections. You can also make multiple selections with the Quick Mask Mode by simply using the Paintbrush Tool and the color white.
When it is easier to select the background than the picture that you want, you can invert your selection. This will unselect the area you have selected, and select the area that is not selected. Also, if you find are trying to select an area and you get a message that says that there are not pixels to select; you may need to deselect another area that you didn’t know was still selected. This is done by going to the Select section and choosing Deselect.
